An MRI performed on Wednesday revealed that New York Rangers forward Ryan Callahan suffered a shoulder subluxation and is expected to be sidelined for 10-14 days, NHL.com reported. Callahan was injured while fighting with Maxime Talbot during Tuesday night's 2-1 win over the Philadelphia Flyers. The players fell to the ice during the fight, and when Callahan arose he held his left arm close to his body. "We were holding each other up and his shoulder popped out or something," Talbot told NHL.com. "It was unfortunate. I let him go. I kind of felt it, but then I saw his face as well." Callahan scored his second goal of the season in the second period Tuesday. He had 29 goals and 25 assists in 76 games last season.
